极端多信使天体物理学探测器（POEMMA）旨在精确观测来自太空的超高能宇宙射线（UHECR）和宇宙中微子，并在整个天体天空中具有灵敏度。POEMMA将观测由UHECR和潜在的20 EeV以上的UHE中微子产生的广泛空气簇射（EAS）产生的空气荧光。此外，POEMMA有能力观察到切伦科夫信号从向上移动的EAS引起的地球相互作用的τ中微子超过20 PeV。POEMMA航天器的设计是为了快速重新定位，以跟踪瞬态中微子源，并获得目前无与伦比的中微子通量灵敏度。POEMMA是作为美国航天局天体物理学探测级使命开发的，由两颗相同的卫星组成，在525公里高度的轨道上松散编队飞行。每台POEMMA仪器都装有一台宽视场（45毫米）的施密特望远镜，光学收集面积超过6平方米。每个望远镜的混合焦面包括一个用于EAS荧光观测的快速（1 μs）近紫外相机和一个用于切伦科夫EAS观测的超快（10 ns）光学相机。在为期5年的使命中，POEMMA将提供测量，为宇宙中最具能量的事件打开新的多信使窗口，从而能够在这些极端能量下研究新的天体物理学和粒子物理学。
The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to accurately observe ultra-high-energy cosmic rays (UHECRs) and cosmic neutrinos from space with sensitivity over the full celestial sky. POEMMA will observe the air fluorescence produced by extensive air showers (EASs) from UHECRs and potentially UHE neutrinos above 20 EeV. Additionally, POEMMA has the ability to observe the Cherenkov signal from upward-moving EASs induced by Earth-interacting tau neutrinos above 20 PeV. The POEMMA spacecraft are designed to quickly re-orientate to follow up transient neutrino sources and obtain currently unparalleled neutrino flux sensitivity. Developed as a NASA Astrophysics Probe-class mission, POEMMA consists of two identical satellites flying in loose formation in 525 km altitude orbits. Each POEMMA instrument incorporates a wide field-of-view (45∘) Schmidt telescope with an optical collecting area of over 6 m2. The hybrid focal surface of each telescope includes a fast (1 μs) near-ultraviolet camera for EAS fluorescence observations and an ultrafast (10 ns) optical camera for Cherenkov EAS observations. In a 5-year mission, POEMMA will provide measurements that open new multi-messenger windows onto the most energetic events in the universe, enabling the study of new astrophysics and particle physics at these extreme energies.
